ROLLER-STAND FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 241,851, dated May 24, 1881.

Application filed January 10, 1881. (Model) To all whom it may concern:

Be it known that we, JEREMIAH EssEx, of North Bennington, in the county of Bennington and State of Vermont, and ALBERT BALL,

of (llaremont, in the county of Sullivan and State of New Hampshire, have invented a new and useful Improvement in Roller-Stands for Spinning-Machines and we do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The invention which is the subject of this applicatiomrelates to roller-stands for spinning machines, roving machinery, &c., in which both sets of back and intermediate rollers are capable of convenient adjustment as to distance from the set of frontrollers, in order to better suit the particular staple of cotton employed, and thereby produce a better yarn with less waste; and the noveltyin this rollerstand consists in the mechanism employed for producing the adjustment above referred to, and in the various operative combinations of the essential elements employed.

In order that those skilled in the art may know how to make and use our adjustable roller-stands, we proceed to describe the same more fully, having reference to the accompanying drawings, in which- Figure 1 is an elevation in perspective, look ing at the gear end and the rear of a single stand. Fig. 2 is a top front view of the same 5 Fig. 3,

it a vertical section of the roll-supports on the line 00 w of Fig. 2, and Fig. 4 a separate view of oneof the posts F. Fig. 5 is a cross-sec-.

tion of parts shown in Fig. 3. Fig. 6 is a vertical section on the line as m in Fig. 2.

Like letters denote corresponding parts in each 'figure.

The drawings, Fig. 1, represent a roller-stand having a stationary lower roll-support, A, in which the front roll, B, and top roll, B, are journaled, the upper roll-support', A, gear D for driving the rolls, and bearing E, in which the back rolls, 0, and the back top rolls, 0, are journaled. Thelower roll-support, A, has atongue, a, upon its uppersurface, and the upper roll-support, A ,a corresponding groove, 1), in its lower 5o surface, sothattheupperroll=supportmay have movement hack and forth upon the lower rollsupport in the direction of an inclined plane, and in its movements carry the back top rolls. ,This movement back and forth is effected by the following mechanism:

Posts F F pass up through a longitudinal opening, 0, in each lower roll-support, A, which opening is considerably larger than the posts F F in its smallest diameter, and in its largest diameter two or three times the diameter of the posts F F, which posts have extending from one side a fulcrum-pin, d, which engages in a corresponding slot, e, on one side of the opening 0. These posts also pass up through the upper roll support, A, in an opening just large enough to permit them to turn in it. They also pass through the box-covers G, and are secured upon them by a pin, f, preferably placed above a suitable washer. Consequently, when these posts are moved back or forth in the opening c, the upper roll-supports, A A, are correspondin gly moved back and forth. To produce this movement of the post, levers H H are firmly secured to the bottom of the post, and to the outer end of these levers a link, I, is pivoted. It follows that when this link is moved in either direction the levers are moved sidewise, then in turn partially revolve the posts, and the posts, being detained by the fulcrum-pin d, swing back and forth in the opening 0, and consequently both of the upper roll-supports and the back top rolls are moved out and in a greater or less distance from the front roll and the front top roll.

At the end of one of the levers H we put an 8 indicator, g, and below that an indicator gageplate, J, over which the indicator traverses,

- and to which it may be secured at any point by a thumb-screw or other ordinary device.

The posts F F also serve to hold the springsupports or roller-frame K, in which the clearin g-roll L is journaled and held with an elastic pressure against the front roll, B.

It is to be understood that the link I may be continued along the front of a long line of 5 stands, being pivoted to levers H H in each stand, as described, so that by one movement of the link I a similar adjustment may be made at the same instant to all of the back top rolls in all of thestands.

The advantages of the mechanism described will be obvious to those acquainted with the ordinary structure of roller-stands, and the difficulties and delays attending the adjustment of them, and the construction and arrangement of the roll-bearings, wherein the front and front top rolls arein a tixed and stationary bearing, and the other rolls in bearings moving upon an incline, will have a special advantage in this, that all the movable rolls will move in the same line of direction and always be in line.

Having thus described our roller-stands, what we claim as new therein, and desire to secure by Letters Patent, is-

1. The combination, with the lower fixed rollersupport and the upper movable rollersnpport, of a post passing through a longitudinal opening in the roller-blaring supports, which opening is of larger diameter in its shortest axis than the diameter of the post, said post having a fulcrum-pin and a lever secured upon such post, substantially as and for the purposes described.
